Outcome Measures

Primary Outcomes (4)

• Percentage of Participants Who Experienced at Least 1 Treatment-Emergent Adverse Event (TEAE)

  An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an AE with an onset that occurs after receiving study drug.

  Baseline up to 30 days after the last dose (Up to 48 days)

• Percentage of Participants Who Met the Markedly Abnormal Criteria for Safety Laboratory Tests at Least Once Postdose

  Clinical Laboratory parameters included tests for chemistry, hematology and urinalysis. Markedly abnormal values during treatment period were categorized as: alanine aminotransferase (ALT)\>3.0 U/L\*upper limit of normal(ULN), albumin\<25 g/L, alkaline phosphatase \>3.0 U/L\*ULN, aspartate aminotransferase \>3.0 U/L\*ULN, bilirubin \>3.42 umol/L creatinine \>177umol/L, gamma glutamyl transferase (GGT) \>3 U/L\*ULN, glucose \<2.8 mmol/L, \>19.4 mmol/L, potassium\<3 mmol/L, \>6 mmol/L, sodium \<130 mmol/L, \>150 mmol/L, protein \<0.8 g/L,\* lower limit of normal (LLN), \>1.2 g/L\*ULN, erythrocytes \<0.8 (10\^12/L)\*LLN, \>1.2 (10\^12/L)\*ULN, hematocrit (%) \<0.8\*LLN, \>1.2\*ULN, hemoglobin \<0.8 g/L\*LLN, \>1.2 g/L\*ULN, leukocytes \<0.5 (10\^9/L)\*LLN, \>1.5 (10\^9/L)\*ULN, platelets \<75(10\^9/L), \>600(10\^9/L). Only categories with values have been reported.

  Baseline up to 30 days after the last dose (Up to 48 days)

• Percentage of Participants Who Met the Markedly Abnormal Criteria for Vital Sign Measurements at Least Once Postdose

  Vital signs included temperature, pulse rate and blood pressure. Markedly abnormal values during treatment period were categorized as: Pulse Rate (beats/min) \<50-\>120, Systolic Blood Pressure (SBP) (mmHg) \<85-\>180, Diastolic Blood Pressure (DBP) (mmHg) \<50-\>110 and Temperature (degree centigrades) \<35.6- \>37.7.

  Baseline up to 30 days after the last dose (Up to 48 days)

• Percentage of Participants Who Met the Markedly Abnormal Criteria for Safety Electrocardiogram (ECG) Parameters at Least Once Postdose

  A 12-lead ECG was performed. Markedly abnormal values during treatment period were categorized as: ECG Mean Heart Rate (beats/min) \<50-\>120, PR Interval, Aggregate (msec) \<=80-\>=200, QRS Duration, Aggregate (msec) \<=80-\>=180, QT Interval, Aggregate (msec) \<=300-\>=460, QTcF Interval, Aggregate (msec) \<=300-\>=500 OR \>=30 change from baseline and \>=450 milliseconds.

  Baseline up to 30 days after the last dose (Up to 48 days)
